Prior to yellowing the plant looked very droopy for 2 wks.

Yes probably overwatering. Wait that ur soil getting dry before try with higher fertilizers concentration .
I would wait at least 4 days .
Personally I weigh the jar to be sure that it dry enough , just to be sure .
Try to give her more light .
Good luck
